Specification of Letters Patent.

Application filed March 9, 1917. Serial No. 153,562.

To all whom it may concern:

Be it known that I, GRANT SIPP, a citizen of the United States, residingat Paterson, in the county of Passaic and State of New Jersey, haveinvented certain new and use ful Improvements in Warping andBeamingMachines, of which the following is a specification.

This invention consists in improvements in machines for warping andbeaming, the same having for their objects, first, so to construct acarriage structure for such machines with relation to the usual pair ofrods or other ways on which it travels as to reduce to the minimum bothfriction and lost motion, thus to obtain a free and perfectlyrectilinear movement of the carriage structure and more accuratedisposition of the warp; second, to provide a certain novel adjustmentof the reed in the reed or warping carriage; third, to provide meanswherebyto facilitate the control of a warping machine reel, and, fourth,to provide a means whereby, in section Warping, the attendant can withincreased facility accurately gage the resetting positions of thewarping carriage.

In the accompanying drawings,

Figure 1 is a side elevation of. the warping means, embodying myimprovements, of a machine of the kind indicated;

Fig. 2 is a plan view of the warping carriage, the gage, a part of themeans concerned n the control of the reel, and the means forsupporting'and'causing traverse of the carriage;

Fig. 3 is a rear elevation of the carriage and said means;

Fig. i is a sectional view on the line 4-4 of Fig. 2; V

Fig. 5 is an end elevation of the gage;

Fig. 6 shows a side elevation, as seen from the inside of the frame inFig. 1, of the means for controlling the reel;

Fig. 7 is a plan view of said means; and,

Fig. 8 is a vertical sectional view thereof.

a is the frame of the machine, vb'the reel, and c a suitable brakeengaging the brakeband (Z of the reel. According to a wellknownconstruction, the reel is driven by the peripheral contact of frictionwheelc .with the band d of the reel, the friction wheel 0 and a conepulleyj being fast on shaft 9 which is journaled in a fulcrumed arm h.The parts e, f, 9, during Warping,

sure being removed from the treadle and the friction wheel falling outof contact with the band cl, the brake brings the reel immediately to astop.

There is the usual pair of parallel stationary shaftsm affording ways onwhich travels, parallel with the reel axis, the warping carriage at, itstraverse being effected from a rotary screw ovjournaled in the framebetween the shafts m and having a sprocketandl-ihain connection 2) Withthe shaft of the rec The carriage n is equipped on the under side with abracket structure q cored to receive the rear shaft on, and in each endthereof are journaled. four rollers 1" engaging the top, bottom, frontand rear sides of said rear shaft. Forward ofthe two-point anti-frictionbearing means thus afforded there is arranged in the carriage anotherrollers which runson the top of the front shaft m. The rollers r and 8permit the carriage to travel substantially without friction along itsways, while the two sets of rollers 1' also serve to hold the carriagefrom any lost motion whatever-an item of great importance in warping,since the slightest unintended movement of the carriage other thanperfect rectilinear movement is likely to lead to serious defects in thewarp, as by overlapping or undue spacing of the threads, in laying it onthe reel; further, the construction is such that the carriage can, ifnecessary in effecting repairs, beelevated on the rear shaft m as afulcrum, having first removed the screw, 0.

For the adjustment of. the reed t, toward and from the reel said reed ismounted in a bracket a arranged to slide on the elevated longitudinallyslotted portion of a bar go bolt d t the t p of arriage n ne pendicularrelation to the reel, said bracket being equipped with suitable means tofor clamping it to the bar.

The warp carriage is disconnectively con nected with the screw 0 by theworm-wheel y arranged on a spindle 2 on which isthe. hand-nut 2, thespindle being set in a bracket 3. depending from the carriage and whichis abutted on either side by the worm-wheel and nut. When the carriageis to be traversed by the screw the worm-wheel is clamped fast to thecarriage by tightening upthe nut; in order to render the carriagemovableindependently of the screw, the nut is loosened, permitting theworm-wheel to turn freely on the spindle a.

In section warping, the sections of warp aresuccessively laid on thereel side by side, and due to the traverse each is wound helicallyvonthe reel. The start of the winding of each section should begin in suchrelation to the beginning of the preceding section that, their twoadjoining lateral threads will be spaced exactly the same as any twothreads in either. The gage shown in Figs.

, 2 and 5 is designed to promote accuracy in re-setting the carriage tothe proper starting point following the winding-on of one section andbefore beginning to Wind the next. There is a member l formed with acollar 4: to embrace one shaft m and a fork 4 (penetrated by but notengaged with-the threading of screw 0) to engage the other (Fig. 5'),and projecting laterally from it, parallel with said shafts, a rigid rod5. There is also a device in the form of a collar 6 slidable on oneshaft on and penetrated by said'rod', and between this collar and member4 and also penetrated by said rod another member 7 Members 4 and 7 haveset screws 8 and 9, respectively, to bind them immovably to the shaft m;collar 6 has a set screw 10 to secure it in fixed relation to the rod.In the present instance, the carriage traverses from left'to right, andis adapted to be re-set from right to left. Be fore. starting the firsttraverse collar 6 is secured to the rod, and member 42 to the shaft by,adjusting their set screws, collar 6 abutting the carriage (at bracket3) and being spaced from member l so that withmember 7 abutting eithermember a or collar 6 there would be a space between the other of theselatter and member 7 equal to they width of each section. After the firsttraverse, of the carriage is completed 1nemher 7 is made to abut member4 and secured by its screw 9 and then, having released screw 8, member 4is shifted to the left, carrying with it collar 6, until the latterabuts member 7 2 The carriage is now re-set until it abuts collar 6,thus covering its traverse distance plus the width of each section andcomingin its new position exactly where it should'be for properlystarting'thenext secnaeases tion. When the secondv traverse iscompleted, member 7 is re-set and secured to the shaft in contact withmember 4, then mem her 4 shifted again to the left until collar 6 abutsmember 7 and finally the carriage moved back into contact with collar 6,being then in exact position for the winding of the third section. Thisoperation is repeated for gaging the new position of the carriagefollowing each traverse.

In order to keep the reel rotating by automatic. means for holding thelever depressed and yet provide for facile and quick release of thetreadle and prompt stopping of the reel I provide the followingmechanism: The free end of the'lever 2' plays in a vertical slot of abracket 11 and is overhung by alug 12 011 the bracket. lhere is a latch13 fulcrumed in this bracket on a vertical axis, one endunderlying thelug 12 and having a lateral projection 14 formed with an under-- neathshoulder 15; theother arm-of the latch is connected with a pin 16'projecting from the bracket by a light spring 17 which holds the latchnormally in the position shown in Fig. 7, and connected-to it is ahorizontal op erating rod 18 which extends across the machine andmay besupported bya hook19depending from the warping carriage. If the operatordesires to leave the reel in motion without holding his foot on thetreadle, he depresses the treadle and by'shifting rod 18 -to the rightswings the end of the latch having the projection 14: into such positionthat such projection will. overlie the (depressed) lever i, upwardlyabutting the lug 12. The friction offered by lever z and lug 12'wil1 besufiicient to prevent spring 17 from retracting latch 13. The frictionwheel 6 will thus be held against the band of the reel',,keeping thelatter in rotation. To stop thereel, the operator has only to move rod18 tothe left to clear projection 14' from'lever' i' so that spring Zwill cause the free end of'l'ever i to be'raised and the friction wheelto fall out of contact with the band d," or' the same result can beaccomplished by depressing and immediately releasing the treadle j, thespring 17 operating in the interim between depressing and releasing thetreadle to 'retract latch 13 out of detent relation to lever i. j
